Asteroid 2002 MN’s Near-Earth Flyby on June 15, 2002

On June 15, 2002, an asteroid known as 2002 MN made a remarkably close approach to Earth, passing at a distance of approximately 121,000 kilometers (about 75,000 miles). This distance is roughly one-third of the distance from the Earth to the Moon, highlighting the proximity of the encounter.

Discovery and Characteristics

• Discovery: Asteroid 2002 MN was discovered on June 17, 2002, two days after its closest approach, by the Lincoln Near-Earth Asteroid Research (LINEAR) program in Socorro, New Mexico.
• Size and Composition: The asteroid is estimated to be about 73 meters (approximately 240 feet) in diameter. Its size is significant, as it could have caused considerable regional damage had it impacted the Earth.

Implications and Context

• Detection After Flyby: The fact that 2002 MN was detected after it had already passed Earth illustrates the challenges in tracking near-Earth objects (NEOs). This incident emphasized the need for improved asteroid detection systems to identify potentially hazardous asteroids earlier.
• Near-Earth Objects (NEOs): 2002 MN is a part of a larger category of asteroids called near-Earth objects, which have orbits bringing them close to the Earth’s orbit. The study and monitoring of NEOs are crucial to assess potential impact risks and devise mitigation strategies.

Historical Significance

• Enhanced Awareness: The close flyby of 2002 MN contributed to heightened awareness of the potential threat posed by NEOs, reinforcing the importance of global efforts to improve tracking and detection technologies.
• Astronomical Research: The event provided valuable data for astronomers and helped refine understanding of the dynamics of such objects in space.

In summary, the near-miss of Asteroid 2002 MN on June 15, 2002, serves as a poignant reminder of the importance of vigilance in monitoring space for potential asteroid impacts, underscoring the ongoing efforts to safeguard our planet from cosmic hazards.
